1-Wire RS-232 Adaptor 1.0

Two variants of RS-232 adaptors to interface to 1-Wire networks.

Schematic and layout were drawn using the freeware version of Eagle.

Prototype

Common prototype for both the passive and active variant:

SMD parts mounted on adaptors:


Passive RS-232 Adaptor

Schematic

Board

The board is completely routed in 2.54 mm raster. Therefore it's easy to build it on experimental boards:
